Why doesn't version 2.0 of the Power Delivery Network (PDN) Tool support a VCCIO setting of 3.3V for Arria® V, Cyclone® V, or Stratix® V devices?

Description

Due to a bug in version 2.0 of the Power Delivery Network (PDN) Tool, a VCCIO setting of 3.3V is not supported for Arria® V, Cyclone® V, or Stratix® V devices.

Resolution

To work around this problem, select a VCCIO setting of 3.0V. Selecting 3.0V for VCCIO instead of 3.3V will result in a marginally lower Ztarget, which is beneficial for PDN design.

Additional Information

The problem has been fixed in PDN Tool V14.1.
